Walking patrols have been increased near the Newport Centre Cinema during showtimes, Jersey City police spokesman Lt. Edgar Martinez said, adding that police are coordinating efforts with private security at the Newport Centre Mall.

Martinez declined to give any more information about the heightened security measures.

Mary Meluso, a spokeswoman for the Liberty Science Center, said Friday that all moviegoers at the center have to pass through metal detectors and there are security personnel in the building at all times.
